Product Description

The DS200SDCIG1ABA is a DC signal input printed circuit board designed for GE Speedtronic Mark V turbine control systems. It serves as a dedicated signal acquisition module, collecting multi-channel DC discrete input signals from field turbine auxiliary equipment. The board processes and transmits status signals to the main controller to support turbine interlock judgment, condition monitoring and safety protection logic execution.

Adopting industrial-grade circuit design with built-in signal filtering and surge protection circuits, the board can adapt to complex electromagnetic environments in power plants. It maintains stable signal acquisition accuracy during long-term continuous operation. As a standard spare component, it is widely used for maintenance and aging hardware replacement of gas and steam turbine control racks.
